I have a header I want to make a copy of (my own design and creation not looking to copy anyone), so I am looking for a tool I can place on the pipe that will tell me what the angles of the bends are.

For example if one primary pipe has 4 bends in it, a tool that will tell me exactly what the angles on those bends are.

Hope this make sense.

 

Tig wire ( any stiff wire ) and a protractor
Just line it up down the center line of the pipe and lay it on the protractor.

 

There are several manufacturers that make measuring tools like a faro arm for reverse engineering tubular assemblies. They are at least 35K.

The least expensive way is take a 90 degree bend and measure around the outside. Take the length around the outside and divide it by 90 and you will have the value of each degree.

Example
distance around the perimieter of a 90 degree bend = 6.125 " / 90 = .068" per 1 degree.

now measure a bend 4.313" / .068= 63.4 degrees

you will need to convert measurements to decimals
1/64 = .015625
1/32 = .03125
1/16 = .0625

 

You can pickup an angle finder from most hardware stores - they are yellow/orange and have a swinging arm that you line up with the centerlines of the bend. You can get +/- 5 degrees or better with one of these.

the last 2 faro arms I bid on at auction, only went for about 5-7k. I want one but cant afford that much on a toy right now
